应用MossBag监测元素汞的干湿沉降.结果表明:矿区大气汞浓度200—1135ng·m-3时汞的湿沉降为1700μg·m-2·a-1;干沉降987μg·m-2·a-1.而当距矿区67km,大气汞浓度3.4—4.0ng·m-3时,其干沉降21μg·m-2·a-1,湿沉降33μg·m-2·a-1,湿沉降占总沉降61%—63%,干沉降占37%—39%,元素汞的干湿沉降与距汞源的距离明显相关
Application of MossBag monitoring elemental mercury wet-dry deposition. The results showed that the wet deposition of mercury was 1700μg · m-2 · a-1 and the dry deposition was 987μg · m-2 · a-1 when the atmosphere mercury concentration was 200-1135ng · m-3. When 67km away from the mine and 3.4-4.0ng · m-3 atmospheric mercury concentration, the dry deposition was 21μg · m-2 · a-1 and the wet deposition was 33μg · m-2 · a-1. The total sedimentation 61% -63%, dry deposition accounted for 37% -39%, elemental mercury wet and dry deposition and the distance from the mercury source was significantly correlated
